- animated object emitters from Houdini, with means to influence emission direction (i.e. via point normals)- not all animations seem to come across to RF (i.e. animated bend sops). Caching that out to bgeo first and then use the RF exporter doesn't change that flaw either- velocity/force fields from Houdini working in Realflow (I read this can be done via vdb, but what's the workflow here?)
